This was accompanied by the rejection by most architects of traditional forms in favour of "international modernism", characterised by simple outlines, uncluttered internal spaces, absence of colour, and flat roofs.
Therefore, the final study sample might not be fully representative of all pregnant women in the study areas, but its internal validity (absence of bias) is not necessarily affected.
The design of a cluster randomized study was chosen because with this type of study internal validity (absence of confounders) can be optimized, contamination of interventions associated with patient randomization is not possible.
The desirable state is "constancy," internal peace and absence of conflict.
The increased strength might be due to improvement of the interfacial transition zone, enhanced hydration due to internal curing, and absence of shrinkage-induced microcraking (Lura 2003; Lura et al. 2004).
As an internal control, the absence of PrPres deposition was also confirmed in the white matter of the cerebellum (figure 1 A).
The presence of RD9 (i.e. M. tuberculosis) gives a product size of 396 bp (RD9 FlankF + RD9 Internal) and its absence (M. africanum, M. bovis) gives a product size of 575 bp (RD9 FlankR+RD9 FlankR).
The remainder load (0.31) was based on internal statistics on absence from work due to vacation, sickness etc. Valuation of formal care was based on gross market wage rates from national collective agreements between Danish local government and the respective professional associations except for teaching activity at courses, which was valued using market prices.
Introns of lincRNA genes provide an internal control: the absence of correlation for the intronic sequences indicates that the observed connection between evolution and expression has to do with structure and function (or robustness to malfunction) of the mature lincRNA molecules.
Similarly, Los Angeles uses internal records on school absences and nurse visits to identify potential enrollees.
